Michigan might be playing the wrong Florida team at the start of the 2017 football season.

Almost a week after Wolverines’ head coach Jim Harbaugh civilly responded to Florida State tight ends coach Tim Brewster on Twitter after Brewster took at shot at Michigan during the 2017 NFL Draft, Brewster was at it again.

This time, he tried trolling Michigan by tweeting a photo of the team’s Orange Bowl rings on Wednesday.

Adding fuel to an already burning fire, Brewster, the former head coach at Minnesota, struck a chord, but not with Harbaugh. Instead, Brewster was roasted on Twitter, quite masterfully, by Michigan offensive lineman Grant Newsome, who took this feud to a whole new level.

Newsome reminded Brewster that the Seminoles’ tight ends didn’t catch a pass in the Orange Bowl, and then went for a real low blow.

Brewster, who went 15-30 as the Gophers’ head coach, was fired midway through the 2010 season. He has yet to respond to Newsome’s scathing reply.

There’s not much for Brewster to boast about, though. While the Seminoles defeated Michigan 33-32 to win the Orange Bowl on Dec. 30, he’s 0-2 as a head coach in bowl games, as well as 0-2 in bowl games when he was a player at the University of Illinois.

Whether or not Brewster can be considered the worst head coach in Big Ten history is another debate for another time. However, this Twitter feud is quickly working its way to being one of the offseason’s best trash-talking exhibitions.
